In a report released February 28 and reported by Computerworld, Austrian researcher Andreas Cleminti from AV Comparatives rated Windows Live OneCare dead last out of 17 anti-virus programs, the only program in the comparison to receive no certification from Cleminti.

The report, available online in a report or in pdf form, rated G Data Security’s AntiVirusKit (AVK) the top performing AV program, catching 99.5 percent of malicious code in the comparison tests. OneCare came in well behind all of the other products, catching only 82.4 percent of the malware.

According to Computerworld, Microsoft responded to the results, saying:

“We are looking closely at the methodology and results of the test to ensure that Windows Live OneCare performs better in future tests,” a Microsoft spokesperson said.

A quick search on AV Comparatives shows a number of anti-virus products touting their results in previous tests, from Nod32 to Kapersky, and AV Comparatives have been posting testing results since February of 2004. This appears to be the first test in which OneCare has been included.
